Hey everybody,
Have had Tinnitus for 35+ years, I found that good room treatments, I had cork wall paper installed, cuts down on refection and gives more of a "comfortable" soundstage. This is my opinion but I think that the situation might be a little different. The sensitivity of the ear at those high frequencies can be altered by basically tricking your mind and hearing to listen to other frequencies in the spectrum. Martin Logans I think are spectacular for the situation because you have one panel dedicated to the midrange and up. I can say that fatigue happens I about 2-3 hours, unless the Bourbon is out!
